If you want open-ear listening and offline music for sleeping, choose AYI True Bone Conduction; if you need a sealed in-ear fit with noise-control modes for everyday listening, choose Thunelec Earbuds. For most people specifically looking for something to wear in bed, I lean toward AYI’s open-ear design because it does not place silicone tips inside the ear. But neither product is described as a sleep-specific headphone, so your comfort will depend on how you sleep and what you expect to hear.
• AYI’s biggest strength: open-ear bone-conduction listening, plus Bluetooth and a 32GB MP3 mode for offline playback. Trade-off: its design does not seal the ears, so it is not the pick for blocking out surrounding sound.
• Thunelec’s biggest strength: in-ear listening with ANC, ENC, transparency mode, and five EQ presets. Trade-off: its silicone tips sit inside the ears, which may not suit everyone in bed.
• Battery and controls: AYI lists up to 8 hours of playtime and has a screen showing battery, mode, and volume. Thunelec lists 6–8 hours per charge and up to 48 hours with its case; its screen controls playback and settings, but volume must be adjusted from the case screen or connected device.
• Water resistance: AYI is rated IPX8 and is designed for swimming. Thunelec is rated IPX7 for sweat, rain, and splashes.
• Who each pick is for: choose AYI if open ears, offline listening, or swimming matter most; choose Thunelec if noise-control options, in-ear sound, and case-based charging suit your routine.
AYI takes a different approach from conventional earbuds. Its open-ear bone-conduction design sends sound through vibration at the cheekbones, leaving the ear openings uncovered. That can appeal to someone who dislikes having ear tips in place or wants to keep more awareness of surrounding sounds while listening. For sleeping, that distinction is the main reason to consider it: there is no silicone tip sitting in the ear canal. It is not a guarantee of comfortable sleep, though, especially for someone who sleeps on their side or finds a headphone frame awkward against a pillow.

Its Bluetooth 5.4 connection is paired with an MP3 mode and 32GB of built-in memory, so it can play stored audio without relying on a Bluetooth connection. That is useful for swimming, where a phone may not be a practical listening companion, and for a bedtime routine where you would rather start saved audio than keep a phone connected. The screen shows battery life, playback mode, and volume. The listed battery life is up to 8 hours per charge.
AYI makes the most sense for someone who values open ears, offline playback, or the IPX8 swimming design. I would skip it if the main goal is to reduce surrounding noise: an open-ear design is not intended to seal out sound, and the product information does not describe a dedicated noise-blocking fit. It may also be a poor match if you specifically want conventional in-ear bass or a snug silicone-tip fit.
Thunelec is the more conventional choice for someone who wants earbuds seated in the ears. It includes three sizes of silicone tips, ANC and ENC, and a transparency mode. ANC is intended to reduce some surrounding noise during listening; ENC is described for clearer calls, while transparency mode lets outside sound through. Those options give it more ways to adapt to commutes, desk work, or calls than AYI’s open-ear design. For sleep, though, its sealed in-ear shape is a personal-fit question: some people may prefer that isolation, while others may dislike having tips in their ears against a pillow.
The charging case adds a touch screen for playback, track changes, calls, and noise-control settings. It also shows battery information and includes extra functions such as a timer and headphone search. There are five EQ presets—standard, classic, jazz, rock, and pop—and Bluetooth 5.4. The earbuds list 6–8 hours of continuous use on a charge, with up to 48 hours total when including the case. A key control limitation is easy to miss: the earbuds do not support direct volume adjustment, so volume must be changed on the case screen or connected device.
Choose Thunelec if you want in-ear listening, several noise-control modes, preset EQ options, and case-based controls. The IPX7 rating is described for sweat, rain, and splashes, not swimming. If your priority is open ears, built-in offline playback, or avoiding ear tips while trying to sleep, AYI is the more natural fit.
• Best for an open-ear design → AYI True Bone Conduction. It uses bone conduction and leaves the ear openings uncovered.
• Best for a sleep setup without ear tips → AYI True Bone Conduction. Its open-ear format avoids silicone tips inside the ears, though sleeping comfort still depends on your position and fit.
• Best for swimming → AYI True Bone Conduction. It is rated IPX8, is designed for swimming, and has MP3 mode with 32GB of built-in memory.
• Best for noise-control choices → Thunelec Earbuds. It offers ANC, ENC, and transparency mode, while AYI’s open-ear design does not provide the same in-ear seal.
• Best for calls and adjustable sound profiles → Thunelec Earbuds. The listed features include ENC and five EQ presets, alongside touch-screen controls for calls and playback.
• Best for long total listening between case recharges → Thunelec Earbuds. Its stated total is up to 48 hours with the charging case; AYI lists up to 8 hours per charge.
• Best if you want volume information on the headphone screen → AYI True Bone Conduction. Its screen displays volume, while Thunelec requires volume changes through the case screen or connected device.
• Best for someone comparing gaming headphones for sleeping → neither is a dedicated gaming or sleep model based on the listed features. AYI’s open-ear design may appeal if you want to avoid ear tips; Thunelec offers noise-control modes but has an in-ear fit. Neither sheet specifies gaming latency or a sleep-specific shape.
In my opinion, I would choose AYI True Bone Conduction for sleeping because its open-ear design avoids putting silicone tips inside my ears, and its MP3 mode offers offline playback. I would not assume that it will be comfortable in every sleeping position, especially for side sleeping. For calls, commutes, or someone who actively wants noise-control options, Thunelec is the more capable everyday listening choice. But for the stated sleep use case, AYI is the one I would buy.
FAQ
Yes. AYI includes 32GB of built-in memory and an MP3 mode for stored audio, as well as Bluetooth 5.4 for wireless listening. That offline option is also relevant for swimming, where keeping a phone connected may not suit the activity.
It is an in-ear model with silicone tips, so whether it works for sleeping depends on your comfort with that fit.
Thunelec lists 6–8 hours of continuous listening per charge and up to 48 hours total with its charging case. AYI lists up to 8 hours on a single charge. Those figures describe different setups, so the case’s additional listening time is Thunelec’s main battery advantage.
